In an ideal transformer, the voltagae and the current in the primary coil are 200V and 2 A, respectively. If the voltage in the secondary coil is 200 V, then the value of current in the secondary coil will be

A

`0.2 A`

B

`2A`

C

`10 A`

D

`20 A`

Text Solution

Verified by Experts

The correct Answer is:
A
The relation for the current in the secondary coil is
`(V_(s))/(V_(P)) = ((i)_(p))/(i_(s)) Rightarrow (2000)/(200) = (2)/(i_(s)) = (2 xx 200)/(2000) = 0.2 A`
